Cooling Water Treatment

We understand that the water treatment of cooling towers is an integral part of process operations in many industries, with the possibility of productivity and product quality being adversely affected by scale, corrosion, fouling and microbiological contamination.

These water treatment problems can be very costly when they cause the loss of heat transfer in the cooling tower, equipment failure, and health and safety concerns.  Nalco uses a unique engineering approach, looking at your cooling tower and water treatment systems from mechanical, operational and chemical angles.  We can provide best-in-class cooling tower water treatment solutions tailored to your open recirculating, once-through, closed loop, geothermal, and process cooling tower systems.

Tower systems, there are typically three main components:

The Evaporator - Typically compresses a gas to allow a heat transfer from one part of the system to another. This part of the system does not require water treatment.

The Chilled Loop - Picks up heat at a source (i.e. air handler for incoming air into a building), transfers that heat via the evaporator.

Open Loop - Open to the atmosphere; contains the Cooling Tower. Heat is transferred outside the building, back into the atmosphere.
